title: Pumilio RNA recognition: the consequence of promiscuity.
abstract: In this issue, Lu and Hall (2011) reveal the structural basis for degenerate RNA recognition by human Pumilio proteins. The structures suggest an appealing model where nucleotides that do not contribute to binding affinity define Pumilio regulatory activity by adopting distinctive conformations with differential ability to recruit regulatory cofactors.
